If you have questions or comments please email the webmaster. A diploid SPOROPHYTE (i.e., a spore-producing plant) produces haploid SPORES, each of which develops into a multicellular haploid GAMETOPHYTE (i.e., gamete-producing plant). Sporophyte plants (explained below) are also diploid. General Characteristics of Bryophytes: Plants occur in damp and shaded areas. Bryophytes. Over evolutionary time, there’s been a trend for plants to develop sporophytes that are larger and more important ecologically that their gametophytes. There are three groups of bryophytes.

You can find bryophytes most often in environments that are too hostile for higher plants, such as sidewalk cracks, the bark of trees, shady logs in woods, the bare faces of boulders, dark crevices in cliffs, and on the newly exposed soil of plowed fields or the bases of overturned trees. S.R. A fertilized egg (which is diploid) is sometimes called a ZYGOTE. Most bryophytes lack complex tissue organization, yet they show considerable diversity in form and The bryophyte sporophyte is smaller (or at least thunner), and simple, looking like a mere appendage of the gametophyte, to which it is permanently attached.
